Linux is one of the few operating systems available at no cost and has become a leading operating system. Linux works on an imbedded system where the operating system is tailored specifically for the system on which it runs.
In order to establish a virtual private network (VPN) on the Linux system, the routing system must be turned on. There is more than one VPN solution available and the choice depends on the needs of the computer user and the ultimate goal of the VPN.
IPSec is one of the oldest VPN standards available for the Linux system and despite the advancement of technology, is still one of the most secure systems when configured properly. IPSec has two implementations called FreeS/WAN and is split into two protocols, Openswan and Strongswan. Each has their own code and kernel stack. The second implementation is KAME and is derived from BSD. KAME only has a kernel stack and shares the necessary code.
IPSec is a protocol that is well established in the world of VPN because of its stability and supports a variety of VPN connections including smartphones, routers and a great many operating systems, including the ever fabulous Linux. IPSec is a reasonably secure platform and allows most data to be tunneled without setting up additional firewall rules.
The SSL based VPN has been gaining in popularity and the best benefit is it only requires one single TCP or UDP port for traffic tunneling. This makes it very easy to traverse most firewalls. There are more than several SSL VPN commercial implementations that support a web based interface and work on just about any browser platform. The one minor drawback is it only allows browsing on web pages located in the remote network. The firewall only needs a single TCP or UDP port and is very flexible in its configuration options.
